3.8 Connection of ducts and hoses
3.8.1 General
Follow the instructions below when attaching ducts or flexible hoses to the unit's air connections.
■
Duct length should be kept as short as possible to minimise static pressure loss.
■
All duct and hose connections must be air tight and vapour tight to ensure full performance.
■
To retain the correct airflow for reactivation air, an air damper must be installed. This damper is to be
installed in the wet air outlet ducting, see
Figure 3.2 and Figure 3.3 . For adjustment of airflow, follow the
instructions in section 4.5, Adjusting reactivation temperature .
■
Ducting for wet air shall be installed at a downward incline to enable condensate to drain. The wet
air ducting should be provided with suitable drainage at low points to prevent the collection of
condensation water. Alternatively, condensation can be avoided by insulating the duct with at least
25 mm of suitable insulating material.
■
Cover the duct opening with mesh to prevent birds and rodents from entering the unit. Position the
opening so that rain and snow cannot enter the lines.
■
The wet air duct or hose must be corrosion resistant and able to withstand temperatures up to 70 °C.
CA CA CAUTION! UTION! UTION!
If there is risk for freezing temperatures, the wet air ducting must be insulated.
3.8.2 Installation examples
Closed airflow system
The dehumidifier is placed in the space to be dehumidified. The wet air is transported outdoors with ducting.
No connection is made to the dry air outlet, see
Figure 3.2 . The advantage with this installation method is a
simpler setup; ducting does not need to be connected to the dry air outlet.
